Subject: Fritz5's strange tablebase

Author: blass uri

6K1/6Q1/8/4q3/8/8/1p6/4k3 b - - 0 1

Fritz5's tablebase says:
(-#2) Qxg7+ (-2) Qb8+ (-2)Qe8+ (-3)Qd5+ (-3)Qe6+ (-31)Qh2 (-36)Qb5
(0) b1B (0) b1Q (0) b1N (0) Kd1 (0) Qe2 (0) Qe3 (0) Qe4 (0) Qf4 (0) Qa5 (0) Qc5
(0) Qf5 (0) Qh5 (0) Qd6 (0) Qf6 (0) Qc7 (0) Kf1 (0) Kd2 (0) Kf2
(-#29) B1R (-#19) Qg5 (-#19) Qe7 (-#17) Qg3 (-#10) Qc3 (-#10) Qd4
(-#10) Ke2


I have no problem with the move Qxg7+ but I do not understand the number 2.
It is clearly not distance to mate and not distance to conversion.

I also do not understand why the mistake in the evaluation of b1B and b1N

Fritz5's tablebase say also in the following position:8/8/8/8/1p2Q2K/q7/1k6/8 b
- - 0 1
b3 (-49)
again I do not understand the (-49)
